When I had an iMac G3 and I typed in machine I got PPC 750. On my Powerbook G4 I got PPC 7450, that made sense, althought it really had a PPC 7447 in it. When I had an iMac G5 and typed in machine, I got PPC 970, again that made complete sense. Now on my Intel iMac I get, i486. So I did a google search of i486...and this was the first hit... http://www.ba23.org/page0203.html HOLY COW! That does not look like my iMac!
